I think the deentrenching ability of infantry reflects their ability to storm and break in the enemy trenches during an attack. Removing this ability might have a big influence.
Yes, I agree. But there wasn't just one line of trenches, so even if they took the front line there would be at least two more lines of trenches to take. This is where we hit the problem of scale in the game. The size of the hexes represent about 30 square kilometres, I believe, and this size would cover the entire depth of the front line and some of the support networks as well. So for defending units to be completely de-entrenched, as happens very frequently in the game, is to say that the defenders have suffered an absolute military catastrophe. Maybe one way of representing this a bit better in the game would be to say that infantry attacks can only de-entrench a hex by 1 level in a turn (by that I mean attacks by 4 infantry units would still only reduce the trench level by one)? And that any other de-entrenchment has to be done by artillery.
Maybe the artillery shouldn't be able to deentrench at all or just to a limited amount. I tried this in a hot seat and the impact of firing eight to ten shells on a heavily entrenched (level 6) corps was still so signicant that it could still be destroyed with consective corps attacks with very little losses on the attackers side.
Another idea is to limit the amount of attacks a single artillery can do in one turn. Right now its limit is its stocked shells.
Yes, a limited amount of de-entrenchment would be good. Maybe an artillery barrage could only destroy half the trench levels (rounded down) in a hex, so that it would make no sense at all to keep on blasting the same hex. Or, also say that artillery cannot de-entrench and destroy strength points with the same shot, so once the de-entrenchment level for that hex had been reached the attacking player would be facing diminishing returns from subsequent artillery fire (because any subsequent de-entrench result would be disregarded and count as a "miss".).
There are a number of interesting ways of addressing this problem, but at the moment, even if you restrict the number of shells that artillery can have by linking that to Logistics Tech, it is still possible from 1915 onwards to line up 2 artillery units on the same target and blast it to oblivion.
